hey, great plugin i have tried the plugin in chrome not sure about other browsers, the transition is smooth but the parent size if changing not so smoothly it's abrupt, I am using chrome v.63

To make the parent height change smoothly i added this ,
`

let Helement = element.outerHeight();

    newParent= $(newParent); 

    newParent.animate({height:Helement},'fast');
